Cerâmicas de A1~ 2~0~ 3~-Y~ 2~O~ 3~-ZrO~ 2~/HfO~ 2~ (incluindo vidros, cerâmicas cristalinas e vidros-cerâmica) e métodos para a fabricação das mesmas. As cerâmicas de acordo com a presente invenção podem ser produzidas, formadas como, ou convertidas em contas de vidro, artigos (por exemplo, placas), fibras, partículas e revestimentos finos. As partículas e as fibras são úteis, por exemplo, como isolamento térmico, cargas ou material de reforço em compósitos (por exemplo, compósitos com matrizes de cerâmica, metal ou poliméricas). Os revestimentos finos podem ser úteis, por exemplo, como revestimentos protetores em aplicações que envolvem desgaste, bem como para gerenciamento térmico. Determinadas partículas de cerâmica de acordo com a presente invenção podem ser particularmente úteis na forma de partículas abrasivas."GLASS, CERAMIC, METHODS FOR MANUFACTURING GLASS, CERAMIC, AND ARTICLE UNDERSTANDING GLASS, GLASS CERAMIC, METHODS FOR MANUFACTURE OF CERAMIC GLASS, AND ARTICLE OF ABRAMATIC GLASS, METHOD FOR THE MANUFACTURE OF ABRASIVE PARTICULARS PLURALITY OF ABRASIVE PARTICULES, ABRASIVE ARTICLE, AND SURFACE GRINDING METHOD ". A1 ~ 2 ~ 0 ~ 3 ~ -Y ~ 2 ~ O ~ 3 ~ -ZrO ~ 2 ~ / HfO ~ 2 ~ ceramics (including glass, crystalline ceramics and ceramic glass) and methods for their manufacture. Ceramics according to the present invention may be produced, formed as, or converted to glass beads, articles (e.g., plates), fibers, particles and thin coatings. Particles and fibers are useful, for example, as thermal insulation, fillers or reinforcing material in composites (for example, ceramic, metal or polymer matrix composites). Thin coatings can be useful, for example, as protective coatings in wear applications as well as for thermal management. Certain ceramic particles according to the present invention may be particularly useful in the form of abrasive particles.
